“…In this sense, Pt/CeO 2 is a promising catalyst for the water-gas shift reaction (WGS). [1][2][3][4][5][6][7][8][9] Supported metal catalysts are traditionally prepared by impregnating a support material with the metal precursor solution, followed by calcination at a relatively elevated temperature and/or reduction under hydrogen (generally above 300 o C). The resulting metal particles are usually heterogeneously dispersed, with a broad particle size distribution.…”

The effect of Ar plasma treatment on the catalytic performance of Pt/CeO 2 has been studied. The catalyst was activated using different procedures separately or in combination: calcination, reduction under pure H 2 and cold Ar plasma treatment. The resulting materials were characterized by X-ray photoelectron spectroscopy, X-ray adsorption near edge structure and temperature-programmed reduction with H 2. The resulting materials were tested in the water-gas shift reaction (WGS). It has been found that the combination of calcination, plasma and hydrogen treatments leads to a very active catalyst for WGS. Furthermore, the catalyst structure-performance relationship has been assessed. The plasma treatment generated electron-enriched Pt particles which show a very strong interaction with the ceria support. This favoured CO chemisorption and increased the reducibility of the support, which takes part in the WGS the reaction by favouring water splitting.

Abstract. Nickel is commonly used as a catalyst in hydrogen production. However, the use of nickel catalysts in the steam reforming process has the disadvantage of coke formation and high cost. Therefore, in this research, Ni/ZSM-5 catalyst synthesis was used to reduce production cost and an addition of cobalt (Co) metal to avoid coke formation. The method consists of a synthesis of ZSM-5 catalyst using hydrothermal process. Furthermore, the crystalline product was impregnated with the metal cobalt, nickel and combination of cobalt-nickel as much as 2% by weight metal/weight of the catalyst. Then the XRD and EDX characterization of Co/ZSM-5, Ni/ZSM-5, and CoNi/ZSM-5 was done followed by catalytic testing in the production of hydrogen from glycerol using steam reforming process. From XRD characterization results showed that Co/ZSM-5 catalyst has a crystallinity of 78.69%, Ni/ZSM-5 catalyst has 70.04% crystallinity and CoNi/ZSM-5 catalyst has 76.99% crystallinity. Catalytic testing on hydrogen production showed that CoNi/ZSM-5 catalyst produced the highest hydrogen concentration of 1,756.33 ppm while Ni/ZSM-5 catalyst produces 1,240 ppm and Co/ZSM-5 catalyst produces 491 ppm.

“…Los resultados obtenidos mostraron que el método de síntesis resultaba clave a la hora de prevenir la sinterización de las partículas metálicas, gracias al tipo de interacciones creadas entre el Ni y el soporte carbonoso. También observaron que la adición de aditivos como el Sn [240] disminuía la sinterización de las partículas metálicas de Ni gracias a la formación de aleaciones NiSn que mejoraban considerablemente la estabilidad del catalizador.…”
